The utility model relates to a natural atmosphere accelerated exposure testing device. The natural atmosphere accelerated exposure testing device can be used for a natural accelerated ageing exposure test in environmental technology. The natural atmosphere accelerated exposure testing device belongs to the technical field of instruments and meters. The natural atmosphere accelerated exposure testing device comprises a device base, an azimuth rotary drive device, a height angle rotary drive device, a cooling fan, a cooling wind pipe, a spray pipe, a sunlight reflector rack, a rotary bracket, a sunlight reflection lens, etc. The azimuthrotary drive device of the natural atmosphere accelerated exposure testing device adopts that the azimuth rotary drive device is arranged and installed on the device base in a planetary type. The height angle rotary drive device is installed on one side of the rotary bracket, and direct connection type arrangement is adopted by the height angle rotary drive device. The cooling fan is directly installed on one side of the cooling wind pipe. An adjustable wind guide plate is arranged on the side surface of the cooling wind pipe. The natural atmosphere accelerated exposure testing device not only intensifies a factor of sun radiation, but also can keep other true natural environment factors, and the natural atmosphere accelerated exposure testing device comparatively exactly reflects the influences of natural environment factors. The natural atmosphere accelerated exposure testing device comparatively exactly evaluates the durability of a material, and predicts the service life of the material. Compared with a natural atmosphere exposure test, the evaluation of the natural atmosphere accelerated exposure testing device to high molecular materials of plastics, paint, rubber, etc. can be accelerated by two to five times.
